citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain newlend v useful Improvements in Burglar Systems, of which the following is a full, clear, and

. exact description.

The invention relates to burglar traps.

The object of the invention is to provide an improved burglar system and trap which is more particularly adapted for banks and whereby the robber will bepr'evented-from improved system for this purpose in which there will be a device, the operation of which will be delayed and which will distract a robber from his purpose, so that the employsof the bank willhave an opportunity to seek protection or assail the robthe invention will appear from'the specification.

In the drawings: Fig. 1 is a diagram of a system embodying the invention. Fig. 2 is. aplan of the mechanism for closing the doors at the. entr ance to the bank. Fig. 3 is an inside elevation thereof; Fig. 4 is a detail'of the distracting device, parts being shown in section. Fig. .5 is a section taken on line 5-5 of Fig. 4. i

The improved system comprises a pair of hinged doors' 7 disposed inwardly of the entrance to the bank a series of switches 8 disposed in different portions of the bank and usually distributed so that one will be available to each employ orgroup of them a device 9 for distracting the robber; a sigoperated after the rob nalling device 10-located at the station where an officer is located or at the police station, and a local signallin device 11 which is er has been trapped in the building. I The invention contemplates the closing of the doors 7 res onsive to any of the switches located throng out the bank oflice or building in advance of the operation of the alarm 11 given "to the bank generally and in ad-:

vance of a signal so as to make it necessary I n so for him to look around to ascertain the source of the distracting signal. The latter is produced by a fire arm which will lead the robber to believe that he is attacked from the rear and make it necessary. for him to turn from the attacked employ in self-defense. To, control the generaljalarm 3 1,492,345 "PATENT QFF-lCE 333mm n BARTON, or cnrcaco, rumors. roaster. svs'rmr. a

and the distracting signal, a thermostat 12 y is utilized to control the electrical circuits for actuating said alarm and distracting device. I i

The system comprises anelectric current generator 13 to which is connected conductors 14: and 15. "Each switch 8 comprises anormally opencontact 16, all of which are connected to the conductorl. Each switch is connected to a conductor 17 in which is I included a helix 18 of a magnet 19 for op-j crating an armature 20 to control the several circuits for the alarms for closing the doors and for operating the distracting device.

An indicator 21 of any suitable type may be included in the conductors-which are con nected to theswitches 8, so that it may be ascertained, if desired, which of the switches 8 was closed to'render the system operative.

in any investigation following a robbery.

The armature. 20 is adapted to hold: a

switch-member 22 which is adapted toengage,"whenreleased, a contact 23,-sothat when the helix 18 is energized,.the switch member 22 will be released and engage the a contact 23. Member 22 is provided with an arm 24 which is adapted to bridge crosscontacts 25 in an electric circuit 26, in which the signal 10 is included, and which may be locatedat any oint remote. from the bank.

The purpose 0 this signal is to notify the .police-station immediately of the operation of the system."

The switch-member 22and contact 23' are adapted to control the mechanism for clos in thedoors 7 as soon as one of the switches 8 is'closed and before the local signals and distracting device in the bank are operated.

The mechanism for operating each door comprisesa solenoid magnet 27 which .is mounted in a frame 28 which is pivoted,'as

at 29, to the door and "is adapted to act upon an armature 30 which is pivoted to the,door l'oo' frame, as :at 31. Each door 7 is usually made of lattice-work, so that it may be easily swing and is hinged, as at32. The

doors are provided with a suitable lock 33 which, when the doors are closed by the solenoids 27, is adapted to secure thedoors so they cannot be opened, except by a proper key. The helix of each solenoid is connected to a conductor 34 which is connected to the switch-member 22 and to a conductor35' which is connected to the generator 13 A5 soon as the switch-member 22 engages con-- tact 23, responsive to the operation of one of the switches 8, a circuit for the operation of the solenoids 27 to close the doors 7 and prevent the escape of the robber will be established as follows: generator 13, conductor 15, contact 23, switch-member 22, conductor 34, the helices of solenoids 27 and conductor 35. This mechanism exemplifies means for closing the doors to the bank before any local alarm is given, so that the robber will be trapped in the bank. A suitable spring lock is provided on the doors so they cannot be opened after they have been closed by the solenoids except by a key.

After the doors have'been closed, the local alarm 11 will be operated to notify all of the occupants of the bank and the device 9 will be operated to distract and confuse the robber. The distracting device is preferably -a firearm adapted to explode blank cartridges and located at some point away from tellers or employs, so that, when it is fired, the robber will look around to ascertain the location from which the shot is fired and to defend himself, if necessary.

The device illustratedas an exemplification of the invention comprises a rotatable I ma azine 37 adapted to hold a series of cartri ges and mounted on a shaft. 38 in a suitable case 39. A ratchet 41 and .apawl 42 on an arm 43 are adapted to rotate the magazine step by step to successively bring the cartridges into position to be-exploded by a hammer 44, which is pivoted in the box, as at 45. A magnet 46 in the case 39' is adapted to operate an armature 47 which is connected to the arm 43 by a link 48 and .is provided with abutments 49 for operating the hammer 44.-. A spring 50 is adapted to retract the armature 47 and the feed mechanism for the magazine; The helix of the ma et 46 is connected to conductor 35.

f A con uctor 51, leading from the helix of the hammer 44 and to move the hammer away from the magazine. In this operation, armature 47 will strike one of the abutments 54 on the switch-member 53 to break the cirEuit for the helix of relay 46 at contacts 52, whereupon the armature 47 will be released and spring 50 will'retract the armature and operate link 48 to operate the hammer 44 to explode a cartr dge m'the' magazine. At' the end of its retractile stroke, armature 47 will engage the I other abutment 54 on the switch-member 53 and restore the switch-member into position to bridge contacts 42- and again close tracting device.

the circuit for the ma et 46, so that the firing of cartridges Wil continue as long as the circuit for controlling the magnet 46 remains closed.

Conductor 51 is connected 'to a contact 56 associated with the thermostat 12. The latter, as well understood in the art, com rises a member 57 formed of metals of di erent coefiicients of expansion and wrapped with a resistance coil 58 which has one of its ends connected to a conductor 59, which is con nected ,to conductor 34, and its other end connected to conductor. 62. The member 57 is also connected to conductor 59 and is adapted to normally engage a. contact 61 which is connected by the conductor 62 to the conductor 35. VVhenthe switch-member 22 is closed, a circuit for the operation of the resistance coil 58 will be established as, follows: generator 13, conductor 15, contact device will be established as follows: generator 13, conductor 15, contact 23, switchmember 22, conductors 34, 59, thermostat member. 57, contact 56, conductors 51, 52 (Fig. 4),. switch-member 53, the helix, of magnet ,46 and conductor 35.

If desired, one or more additional distracting devices 9, similar in construction to the I,

device 9, may be provided in different portions of the bank, the helix of the magnet 46 for each of said devices being connected to conductors 51 and 35. The alarm or signal device 11 for notifying the local employs is included in a conductor 64 which is connected to conductors 51 and 35, so that whenever the distracting device 9 is operrobber while he is endeavoring to ascertain the source of the shots produced by the dis- The invention is not to be understood as restricted to the details set forth, since these maybe modified within the scope. of the appended claims, without departing from the spirit and scope of the invention. 7
